Title: Semiconductor device
Inventor: KOBAYASHI HITOSHI
IPC: H01L23/50
Filed: 1989-08-11
Abstract: PURPOSE:To prevent solder bridges from generating between lead terminals, and improve the solderability of the tips of lead terminals, by cutting a linkage bar in the longitudinal direction of the lead terminal, and separating each of the lead terminals. CONSTITUTION:In a semiconductor device 21, a lead terminal 22a is formed by cutting a cradle as a linkage bar so as to have the same width as an original lead terminal. In a semiconductor device 21', a lead terminal 22a' is formed by cutting the linkage bar in the manner in which the width of a lead terminal is narrowed in taper as it approaches the tip part. In particular, the semiconductor device 21' having the lead terminals 22a' whose tips are narrowed in taper can effectively prevent solder bridges from generating between the lead terminals.

Title: Nonlinear amplifying circuit
Inventor: ISHIKAWA KATSUYA
IPC: H03G11/08
Filed: 1988-08-24
Abstract: PURPOSE:To offset-cancel a non-linear amplifier with a simple means by providing a non-linear amplifier and a voltage divider to generate the output with the output voltage of the non-linear amplifier as 1 of the maximum gain of an amplifier. CONSTITUTION:Resistances R1 and R2 constitute a voltage divider and the voltage of 1 of maximum gain of a non-linear amplifier 14 is outputted from an output edge P. For the input output characteristics of the non-linear amplifier 14, at a central part B, a gain is maximum, and as it is dislocated from it, the gain is minimum, the gain approaches to 0 at areas A and C, and therefore, a voltage VM sets the amplifier to a gain maximum area B. At the time of the non-linear amplifier 14, at the part having a large gain, an input offset voltage must be small and at the part having a small gain, the input offset voltage may be large to the extent. Consequently, at a part B in which the gain of the non-linear amplifier becomes maximum, the offset-cancellation is executed so that the offset voltage can become minimum and then, it is practically sufficient. Thus, without needing a pad for outside-fitting, the cancellation fluctuation due to the temperature,etc., does not occur and the offset-cancellation can be executed.

IPC: F27B3/00
Filed: 1988-08-25
Abstract: PURPOSE:To prevent the damage of a refractory and reduce operation cost as well as fuel consumption by a method wherein the thermal stress evaluating value of the refractory material is obtained by employing model blocks or the like and a condition that the evaluating value becomes less than 50% of the strength of the refractory material is set while actual operation is controlled so as not to apply an excessive temperature difference and/or a sudden temperature change on the refractory material. CONSTITUTION:A corresponding relation between the calculated value of a thermal stress and the condition of actual damage is examined by model test and the ratio therebetween is obtained as the thermal stress correcting coefficient Sk of a refractory material proper. Subsequently, the thermal stress of the refractory material under an actual using condition is operated from the temperature of the surface 4 thereof or a temperature in a furnace 3 and the temperature of the back surface 6 of the refractory material. The operated value is corrected by the correcting coefficient Sk to obtain a thermal stress evaluating value delta. The thermal stress evaluating value delta is compared with the average tensile strength S of the refractory material and a strength is set in an actual operation so that the evaluating value delta becomes less than 50% of the average tensile strength S of the refractory material. The temperatures of the surface 4 and the rear surface 6 of the refractory material are measured and the actual operation is effected so as not to apply any excessive thermal stress on the front and rear sides as well as the inside of the refractory material whereby the damage of the refractory material may be prevented.

The output of the sensor 57 is binarized by a binarizing circuit 60, and a counter 61 terminates a counting by the binarization output, and the counted value indicates the extent of movement of the peripheral surface of the photosensitive body. Contents of a ROM 62 and the counted value of the counter 61 are compared with each other by a comparator 63 to detect the positional deviation in the subscanning direction of write scanning to the photosensitive body 10. The detected positional deviation is corrected based on the positional deviation information and the driving signal of a resist roller to obtain a write signal. When four kinds of electrostatic latent image are formed, the position in the subscanning direction of write scanning is adjusted and controlled at every latent image to obtain the images having high quality free from color deviation.
